Thanks Clarky!
I mustn't have articulated it very well, but what I was suggesting is exactly what you said above - bring the WH and XH together and keep the WK2 Grand section separate and on its own.
They do a XH Commander and WH Grand section on the USA Jeep forum (called XK & WK over there of course) which works quite well.
Hopefully we get enough support to make this happen soon!
Cheers,
Hanna
